Power Steering pump?

I know that the Saginaw "canned ham" pump is a popular swap for many applications. Being a Toyota guy I have been searching for a Volvo ps pump for my build.

Many Toyota guys use a volvo ps pump for this conversion due to the fact that a Toyota high pressure line will bolt up. Volvo is commonly used for the wider pulley matching the v belt more closely than a Chevy.

Does anyone have any knowledge the will share regarding the remote reservoir volvo pumps. It seems (according to some googling) that the the remote res volvo pump is a TC pump that puts out 15 gpm. The canned ham version is more like 20.

Will the remote res pump flow enough to operate a hydro assist? I can't seem to find the answer using google?

Any insight would be greatly appreciated. My time is limited and I would prefer not to go down the wrong path fabricating a mount to use the wrong pump.

Thanks NC4x4!

I don't know much about it but the guy that bought my FJ60 used a Chevy pump & said he had great results.

I have no idea about Volvo pumps for your application but your numbers are way off. TC pumps are in the neighborhood of 2.5-3 gpm. With modifications they start blowing up around 3.5-4. Anyone selling a '4-5 gpm' TC pump is lying. P pumps (canned ham) you can add about .5 gpm to the TC pump numbers.

The highest flowing automotive based pump on the market right now is pushing 10 gpm at idle and up to 13 gpm at 2000rpm engine speed. It still needs a refresh every 500-1000 race miles though.

A stock TC pump will perform fine with hydro assist assuming you size the ram correctly. Meaning, bigger is not better. All you need is a relatively small cylinder to provide adequate assist.

Thanks for the correction Will. I read so much yesterday while researching this ps pump that my brain was scrambled.

IIRC this pump is referred to as a Series II pump and is a newer version of the canned ham.

As far as the ram goes I'm looking at a 1.5x6 from surplus center. This is what I should run right?

Here is the pump in question.

I've done a few hydro assists on toyotas using the stock toyota pump that performed fine. You can drill out the fitting a little bit to get a little more flow if you find you're over running the pump with the box. But sneak up on it. Don't drill too much or it's trash.
 
What ram did you run off the stock pump?

My Toyota is a FJ60 and they have a totally garbage pump. The mini truck pumps are significantly better, but if I have to reinvent the wheel to get steering back I was hoping to upgrade as much as I can (on the cheap).
 
Cool. Thanks Rodney. I will look into it. I can't seem to find much on the volvo pump but it is identical to a sunfire pump. The sunfire even had metric fittings. Off of a street rod parts place the stock sunfire pump flows 3-3.1 gpm. Still can't determine a projected psi or any concrete numbers for the volvo unit.
